Microsensor data format conventions

To facilitate rapid and automated analysis of the microsensor data by the analytical software, the data generated by the measurement software needs to follow conventions listed below.

Concentration profiles data format

The concentration profiles are stored in an *.mpr (micro-profile) file, an example of which is shown below. It is an ASCII text file, and can thus be viewed by any text editor. The columns are separated by Tab (\t).

  • The hash character (#) indicates a comment, lines without # contain the data.
  • Column 1: a profile number within the measurement (1, 2, 3, …, depending on how many profiles were measured);
  • Column 2: a reading number within the profile (1, 2, 3, …, depending on how many readings in one profile were measured);
  • Column 3: depth, in microns;
  • Columns 4 & 5: date & time of the data point, formatted as DD/MM/YYYY hh:mm:ss;(Note: This depends on the regional settings of your computer. Make sure that they are set exactly in this way!)
  • Columns 6, 7, …, N: sensor signals (depending on how many channels were recorded; N=3 in the example above).

Concentration time-series data format

The concentration time-series are stored in an *.dat file, an example of which is shown below. It is an ASCII text file, and can thus be viewed by any text editor. The columns are separated by Tab (\t).

Note: When generated by m-Profiler or DAQ-server, the extension of the data file is automatically changed to 0, then 1, then 2, etc., after a certain number of lines (~5000) have been recorded. This is a safety feature (if, for some unknown reason, a data file is corrupted, only part of the collected data will be lost).

  • The hash character (#) indicates a comment, lines without # contain the data.
  • Columns 1 & 2: date & time of the data point, formatted as DD/MM/YYYY hh:mm:ss.msec; (Note: This depends on the regional settings of your computer. Make sure that they are set exactly in this way!)
  • Columns 3, 4, …, N: sensor signals (depending on how many channels were recorded; N=1 in the example above).
